New research, led by the University of Southampton, suggests that the release of methane from the seafloor was much slower than previously thought during a rapid global warming event 56 million years ago.

250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean. During the summer months this leads to an increased methane concentration in the ocean. But surprisingly, very little of the climate ...

Scientists have calculated that the present day ice sheets keep vast amounts of climate gas methane in check. Ice sheets are heavy and cold, providing pressure and temperatures that contain methane in form of ice-like substance ...

Methane hydrates are a kind of ice that contains methane, and that form at certain depths under the sea or buried in permafrost. They can also form in pipelines that transport oil and gas, leading to clogging. Yet methane ...

Warming ocean temperatures a third of a mile below the surface, in a dark ocean in areas with little marine life, might attract scant attention. But this is precisely the depth where frozen pockets of methane 'ice' transition ...

Like the carbon dioxide in a fizzing glass of soda, most bubbles of gas in a liquid don't last long. But nanobubbles persist. These bubbles are thousands of times smaller than the tip of a pencil lead—so small they are ...

Gas hydrate is also known as the ice that burns. And everything that burns releases energy. A lot of energy is stored in hydrates: a cubic meter of methane hydrate, for example, compresses as much as 168 m3 of natural ...

Large amounts of methane - whether as free gas or as solid gas hydrates - can be found in the sea floor along the ocean shores. When the hydrates dissolve or when the gas finds pathways in the sea floor to ascend, the methane ...
